CHAIR IRON AND LEG.

SPECIFICATION forming part of Letters Patent No. 575,718, dated January26, 1897.

Application filed March 6,1896.

To all whom, it may concern.-

Be it known that 1, MILES A. HANSON, of Port Washington, in the countyof Ozaukee and State of Wisconsin, have invented a new and usefulImprovement in Chair Irons and Legs, of which the following'is adescription, reference being had to the accompanying drawings, which area part of this specification.

My invention has relation to improvements in chair irons and legs.

Chair-irons as now manufactured for the trade generally consist of whatis termed a "hub, said hub having an inner tubular bore usually threadedto adapt a threaded spindle to turn therein, the outer surface of thehub being provided with sockets for the reception of the inner edges ofthe chair-legs. The trade at the present time demands, in order toprovide a salable chair and one suitable for the market, that thechair-legs and the hub or iron shall be a certain distance verticallyfrom the floor, in order that the chairseat, when adjusted to its lowestposition,

will be a predetermined distance above the floor. Now in this form ofchair-iron the tubular bore of the hub merely extends throughout thelength of the hub. It has not been found practicable in the present formof hub to provide the same with an upwardly-extending tube, owing to thefact that the chairseat would thereby necessarily be raised too high topermit said chair-seat, when in its lowest adjustment, to be the properdistance above the floor as required by the trade. While this might beovercome by lowering the hub to within but a short distance of thefloor, yet this would be open to objection, owing to the fact that itwould necessitate the use of chair-legs extending out for a considerabledistance on almost a horizontal plane. The disadvantage of such aconstruction of chair-legs is obvious. In the first place it wouldgreatly mar the general appearance of the chair, and in the second placethe legs would be thereby so spread out as to take up too muchfloorspace. That a chair-iron provided with an upwardly-extending tubeto receive the spindle of the chair, said tube not being designed tohave the chair-legs secured directly thereto, is an advantageousconstruction will be readily-appreciated by reference to my apwings 6.

$erial No. 582,043. (No model.)

plication for patent filed August 29, 1895, Serial No. 560,857, forimprovements in revolving chairs, in which application the verticaladjustment of the chair-spindle is accomplished by certain mechanismengaging the upwardly-extending tube and engaging the spindle within thetube.

It is the primary object, therefore, of my invention to provide aconstruction in which an upwardly-extending tube is employed inconnection with an improved form of chairiron base, which, when thechair-seat is in its lowest adjustment, will not raise said chairseattoo high above the floor, and at the same time a graceful and ornamentalform of chairlegs is preserved, which chair-legs do not spread outunduly, so as to consume too much floor-space. The particular form ofchair-legs adopted by me not only subserve beauty, but, furthermore,possess a distinct advantage, which will be hereinafter more fullypointed out.

The invention incidentally comprehends simplicity, strength, cheapness,and readiness with which the parts may be assembled and disassembled.

With the above primary objects in view the invention consists of thedevices and parts or their equivalents, as hereinafter more fully setforth.

In the accompanying drawings, Figure 1 is an elevation of the invention,the base and hollow post projecting therefrom being in section and thelegs partly broken away. Fig. 2 is a plan View of the complete device.Fig. 3 is an inverted plan of the base of the chairiron, and Fig. 4 is aView of a fragment of one of the legs.

Referring to the drawings, the numeral 5 indicates the base of thechair-iron, which is provided with a series of lateral horizontal Thesewings are provided upon their under sides with recesses 7, preferablyrectangular in shape, and having opposite end walls 8 8 and side walls 99. The base is apertured centrally, and advisably extending upwardlyfrom this aperture is a post 10, preferably tubular, for theaccommodation of the chair-spindle. (Not shown.) The post also extendsfor a short distance below the base and is square in cross-section toform the end walls 8'.

The numerals 11 indicate the chair-legs, which are preferably, althoughnot necessarily, of the form shown. Their upper ends extendapproximately in a vertical plane, and are provided with a series ofupwardly-projecting tongues 12, which are adapted to fit the recesses 7of the base. Each tongue is so formed as to provide an outer endshoulder 13 and two side shoulders ll 14. The shoulders 13 are adaptedto support the outer end walls of the recesses '7 and the shoulders 1tthe side walls 9 of said recess.

It will be noticed that the legs 11 are 1011- gitudinally of asiginoidal form or shape, the

lower curve being upward and the upper curve downward, said upper curvemerging into a straight vertically-extending extremity, the edge of saidvertically-extending extremity provided with the tongues 12. Thisparticular form of chair-legs wherein the upper curve is downwardpossesses a distinct advantage over the ordinary form of chair-legs,inasmuch as the downward curve will allow the legs of a person sittingin the chair to clear the chairlegs and not strike the same when thechair-seat is revolved, as is the case with the ordinary form ofchair-legs, and their formation also permits them to be used with ahorizontal base of the description described, raised but a shortdistance above the floor.

The base is held firmly to the upper ends of the legs by means of bolts15, which pass through the wings and through the legs and receive upontheir lower ends nuts 16, said nuts disposed in suitable recesses 17therefor in the under edges of the legs.

It will be seen that my improved form of chair-iron and supporting-legsis such that the legs may be readily secured in place to the base, andthat the liability of the parts becoming loose or detached is reduced tothe minimum.

By my improved construction I am enabled to provide a chair-base whichneed not be raised too high above the floor, thus bringing the upper endof the upwardly-extending post low enough to allow for the required downadjustment of the chair-seat, and at the same time chair-legs ofsuilieient length may be employed to afford a firm base-support,avoiding the necessity of shortening the length of the chair-legs tosuch an extent as to cause danger of the chair tipping over.

\Vhat I claim as my invention, and desire to secure by Letters Patent,is-

1. The combination, with a horizontal flat chair-base provided upon itsunder side with a series of lateral independent recesses, each recesshaving opposite end walls and opposite side walls, and said base alsoprovided with a post extending upwardly for a desired distance above thebase and for a slightdistance below said base, the portion extendingbelow the base forming the inner end walls of the lateral recesses, ofchair-legs having vertical tongues at their upper ends, said tonguesfitting in the recesses and being so formed as to provide at their basesopposite side shoulders and outer shoulders, the side shoulders of eachtongue supporting the lower edges of the side walls of the recesses, andthe outer shoulders the end walls of the recesses.

2. The combination, with a horizontal flat chair-base provided with aseries of independent lateral win formed with recesses upon their undersides, each recess having opposite end walls and opposite side walls,and said base also provided with a post extending upwardly for a desireddistance above the base, and for a slight distance below said base, theportion extending below the base forming the inner end walls of thelateral recesses, of chair-legs having vertical tongues at their upperends, said tongues fitting in the recesses and being so formed as toprovide at their bases opposite side shoulders and outer shoulders, theside shoulders of each tongue supporting the lower edges of the sidewalls of the recesses and the outer shoulders the end walls of therecesses.

23. The combination with a horizontal llat ehair-base provided upon itsunder side with a series of lateral independent recesses, each recesshaving opposite end walls and opposite side walls, and said base alsoprovided with a post extending upwardly for a desired distance above thebase, and for a slight distance below said base, the portion extendingbelow 'the base formin the inner end walls of the lateral recesses, ofchair-legs each of a sigmoidal form longitudinally, the lower curvebeing upward and the upper curve downward, said upper curve merging intoa straight vertically-extending extremity, the edge of said vertically-extendin g extremity provided with a tongue, the tongues of theseveral legs fitting in the recesses, and being so formed as to provideat their bases opposite side shoulders and an outer shoulder, the sideshoulders of each tongue supporting the lower edges of the side walls ofthe recesses, and the outer shoulders the end walls of the recesses.

In testimony whereof I affix my signature in presence of two witnesses.
